Q78.

A recent report determined that although only 3 percent of drivers on Maryland highways equipment their vehicles with radar detectors, 33 percent of all vehicles ticketed for exceeding the speed limit were equipped with them. Clearly, drivers who equip their vehicles with radar detecters are more likely to exceed the speed limit regularly than are drivers who do not.

the conclusion drawn above depends on which of the assumotions?

A Drivers who equip their vehicles with radar detectors are less likely to be ticketed for exceeding the speed limit than are drivers who do not.

B Drivers who are ticketed for exceeding the speed limit are likely to exceed the speed limit reguarly than are drivers who are not ticketed.

C The number of vehicles that were ticketed for exceeding the speed limit was greater than the number of vehicles that were equipped with radar detectors.

D Many of the vehicels that were ticketed for exceeding the speed limit wre located more than once in the time period covered by the report.

E Drivers on Maryland highways exceeded the speed limit more often than diDd drivers on other state highways not covered in the report

答案是B，我能排除D和E，ABC就很纠结，请帮忙点拨

124. Museums that house Renaissance oil paintings typically store them in enviroments that are carefully kept within narrow margins of temperature and humidity to inhibit any deterioration. Laboratory tests have shown that the kind of oil paint used in these paintings actually adjusts to climatic changes quite well. If, as some museum directors believe, paint is the most sensitive substance in these works, then by relaxing the standards to temperature and humidity control, musuums can reduce energy costs without risking damage to these paintings. Museums would be rash to relax those standards, however, since results of preliminary tests indicate that gesso, a compound routinely used by Renaissance artists to help paint adhere to canvas, is unable to withstand significant variations in humidity.

in the argument above, the two portions in boldface play which of the following roles?

A The first is an objection that has been raised against the position taken by the argument, the second is the position taken by the argument.

B The first is an position taken by the argument, the second is the position that the argument calls into question

C The first is a judgement that  has been offered in support of the position that the argument calls into question; the second is a circumstance on which that judgment is, in part, based

D The first is a judgement that  has been offered in support of the position that the argument calls into question;  the second is that position

E The first is a claim that the argument calls into question; the second is the position taken by the argument

答案是D，想了好久，看了解释也不太明白为啥选这个，拜托了~~~~~~~

我又绕进去了，弱弱的问一下：为什么说装雷达的更容易被罚？因为33%的关系么？

刚看到这个帖子，自己也想呢，不过想明白了，其实是题目给的是装雷达与罚单之间的关系，结论是装雷达与超速的关系，如果说装雷达是A，超速是C，开罚单是B，那么按照三段论，是A-->B,结论是A--->C，假设就应该讨论B与C的关系~~
这样解答对吗~~

这就是所谓的搭桥法，在assumption的题中，当你发现明显的逻辑链断开了，那答案往往就补出断开的部分。

分明是這個最靠譜,這道題不是一般順序的三段論~~

Q78
题目中内容：
现象：
1）3%汽车安装了雷达探测系统；
2）在超速罚单中，33%的汽车是安装了雷达探测系统；
结论：
一般来说，装了雷达探测系统的车更可能超速；
问题的内容：
给个assumption来得到结论？
推理分析：
如果是正常情况（分配均衡），3%的车辆安装雷达探测系统，那么在超车罚单中也应该只有3%的车辆安装了雷达探测系统。
而现在的实际情况是，在超速罚单中有33%的车辆安装了雷达探测系统。
那么说明，在超速罚单中，安装了雷达探测系统的车辆数目超出了正常水平，他们更可能得到超速罚单。
还要注意：超车被罚款，超车，两者不同等同。
答案分析：
A:安装了雷达探测系统的车不太容易因为超速而被开罚单。==>这里只说明了“超速罚单的问题”，自问一句这跟“超车”是同一问题么？好似不是同一个概念哦！
B:因超速而被罚款的驾驶员比起不被罚款的驾驶员更可能超速。==>这里就刚好就“超速罚单”与“超速”问题联系到一起了~~
C:因超速而被罚款的驾驶员比安装雷达探测系统的驾驶员多。==>错误的，安装雷达探测系统的车辆占总车辆的3%，因超速而被罚款的车辆的数目在这里没有提及，两者之间无法比较。而且跟题目中的问题也无关。

我想说，A选项如果是true，那么被t的车辆百分比是不是应该少于3%呢？
我的思路好像和A-B-C是一样的。
很确定自己被绕进去，请拍砖！！

谢谢！这个最靠谱！

对78题是这样理解的。我觉得关键在于regularly这个词，更经常
前提：3%的司机有雷达
     因超速而被罚的汽车中有33%有雷达
结论：有雷达的司机比没有雷达的司机更可能经常超速（注意这个经常超速）
我们要找一个假设，来填补gap
根据前提能得出有雷达的司机更可能因为超速而被罚，而并没有说更可能经常超速，所以要把中间的这个逻辑补全
既：有雷达更可能被罚款----因超速而被罚的司机更可能超速----有雷达的司机更可能超速
这样逻辑就比较完整了。

124 position这个词怎么理解呢？谢谢NN们回答

-- by 会员 xibao (2011/3/14 5:46:30)

that position 指前提到的position，而不是整个 argument 的 position.
